"The journey of higher education is an incredible, impactful and pivotal one," she said.

"Everyone should be afforded the opportunity to receive the education they want, but more importantly the education they have the right to receive.

"And for women and girls in developing countries, this is vital. Providing them with access to education is the key to economic and social development.

"Because when girls are given the right tools to succeed, they can create incredible futures, not only for themselves but also for those around them."

The duchess announced two grants for the Fiji National University and the University of the South Pacific, allowing each of them to run workshops to empower their female staff.

She said: "This means that female faculty members are able to encourage others to follow in their footsteps and enter higher education, and that more women become part of the decision-making process in academic institutions.

"Grants like this ensure that women are provided with the training and skills to operate effectively in their roles, and those with leadership potential are given the opportunity to be heard and recognised at the most senior level."

Earlier the Duke of Sussex laid a wreath of poppies in honour of Fijian war veterans during a solemn ceremony.

Harry was without Megan for his first engagement of the day in which he spoke with veterans, including a number who had served with the British Armed Forces.
